The Theodul Glacier (also spelled ''Theodule Glacier''; (ドイツ語:Theodulgletscher)) is a glacier of the Alps, located south of Zermatt in the canton of Valais. It lies on the Swiss side of the Pennine Alps, although its upper basin touches the Italian region of the Aosta Valley. The glacier descends from the west side of the Breithorn () and splits into two diverging branches above Gandegg: the Upper Theodul Glacier (''Oberer Theodulgletscher''), spilling on a high plateau near Trockener Steg, together with the Furgg Glacier, and the Lower Theodul Glacier (''Unterer Theodulgletscher''), reaching a height of about above the Gorner Glacier. Both branches are part of the Rhone basin, through the rivers Gornera and Vispa. Slightly above the glacier splitting is the Theodul Pass, crossing the border between Switzerland and Italy, and connecting Zermatt to Breuil-Cervinia. On the west, the Theodul Glacier is overlooked by the Matterhorn. The upper section of the Theodul Glacier consists of a flat plateau at around 3,800 metres, named ''Breithorn Plateau''. The plateau lies between the Breithorn, the Gobba di Rollin and the Klein Matterhorn. The Breithorn Pass (3,814 m) separates the Breithorn from the Gobba di Rollin. A 3,795 m high saddle lies between the Gobba di Rollin and the Klein Matterhorn. Between the Klein Matterhorn and the Breithorn is a distinct glacier, named ''Klein Matterhorn Gletscher'', which joins the Lower Theodul Glacier at about 3,000 metres. The Breithorn Plateau area can be easily accessed by several cable cars connecting Zermatt to the Klein Matterhorn. At around 3,500 metres is the ''Plateau Rosa'', whose name derives from the Valdôtain patois term ''Rosà'', meaning "frozen" (as for the nearby Monte Rosa). This area lies between Testa Grigia (3,479 m) and the Klein Matterhorn, south of and slightly above the Theodul Pass. Southeast of Testa Grigia is a saddle named ''Passo di Ventina Nord'' (3,445 m). This area can also be easily accessed by several cable cars connecting Breuil-Cervinia to Testa Grigia. Most of the glacier is part of the year-round ski area〔(【引用サイトリンク】title=Summer Skiing on the Glaciers )〕 marketed as ''Matterhorn Glacier Paradise''. It is the highest in Europe and largest summer ski area in the world, with 21 kilometres of prepared pistes.〔(Summer Skiing ) Zermatt Bergbahnen〕 The culminating point is on the summit of Gobba di Rollin and the lowest is above Trockener Steg. The Matterhorn Glacier Paradise links the ski areas of Zermatt and Breuil-Cervina. Ski lifts connect Trockener Steg, Theodul Pass, Testa Grigia, Klein Matterhorn and Gobba di Rollin. A chair lift also connects Trockener Steg to the Furggsattel (3,349 m), north of the Theodul Pass. Several lakes recently formed at the bottom of the Upper Theodul Glacier, west of Trockener Steg. The largest, named ''Theodulgletschersee'' is 7.76 ha wide and lies at an elevation of 2,851 metres above sea level. It is the highest lake over 4 ha in Switzerland and the largest lake in the valley of Zermatt. The second-largest, named ''Furggsee'' is 2.57 ha wide and lies at 2,874 metres.〔Primary surfaces VECTOR25 (Swisstopo)〕 ==References== *Swisstopo topographic maps (1:25,000) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Theodul Glacier」の詳細全文を読む スポンサード リンク
